OpenAI is reportedly testing a new feature for its AI coding agent, Codex, called Chronicle. This opt-in research preview allows Codex to capture screenshots of a user's screen and use that visual information to build contextual memories, helping the AI understand ongoing work without requiring users to repeatedly explain their tasks. Currently available only on macOS, the feature has drawn comparisons to Microsoft's controversial Windows Recall feature and has raised privacy and cybersecurity concerns.
What is Chronicle and How Does It Work?
According to OpenAI's documentation, Chronicle augments Codex memories with context from the user's screen. The feature periodically captures screenshots, processes selected ones using OCR and other tools to extract text and context, and converts that information into text-based memory files that Codex can reference in future sessions. OpenAI states that screenshots are temporarily stored on-device for up to six hours and then sent to servers for processing, but they are not permanently stored or used for training. However, the generated memory files remain stored locally until manually deleted.
Comparison to Microsoft's Windows Recall
Chronicle has been compared to Microsoft's Windows Recall, which automatically takes screenshots every few seconds to enhance AI assistance. Security researcher Michael Taggart highlighted similarities, noting that OpenAI essentially reinvented Recall for macOS. Unlike Recall, Chronicle is optional and currently macOS-only.
Privacy and Security Risks
OpenAI acknowledges potential risks, including that directories for screen captures and memories may contain sensitive information. The company warns that other programs on the computer can access these files. Additionally, Chronicle may increase the risk of prompt injection attacks if malicious content appears on-screen. Users must manually enable the feature through Codex settings and grant screen recording permissions. It is not available in the EU, the UK, or Switzerland.
Benefits for Developers
For developers, Chronicle could reduce repetitive prompts by helping Codex automatically understand coding errors, files, and workflows. However, users handling sensitive information should carefully review privacy implications before enabling the feature, as screen captures and memory files may contain passwords, private messages, or financial data.
